Specific references to Summer squash throughout Geoff Bond's publications.
Abnormal testosterone production is a major risk factor for prostate cancer. Some compounds, such as lignans, lock up testosterone and stop it from creating damage. Lignans are a kind of plant fiber. The highest concentrations of lignans are found in flaxseed, followed by squash, broccoli, carrots, and asparagus. Studies on flaxseed, which also contain high levels of omega-3 oils and fiber, show that they are indeed great cancer fighters. ~Deadly Harvest p.236
